| Abstract: |
A new cultivar of Clematis named `Hendryetta` that is characterized by a low growing, upright, semi-climbing habit, symmetrical light purple flowers which are fragrant, and medium to dark-green foliage. In combination these traits set `Hendryetta` apart from all other existing varieties of Clematis known to the inventor. |
| Claim: |
It is claimed:
1. A new and distinct variety of Clematis plant named `Hendryetta` as described and illustrated. |
| Description: |
Genus: Clematis.
Species: .times.hybrida.
Denomination: Hendryetta.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Clematis that is grown for use as an ornamental in the landscape. The new cultivar is known botanically as Clematis and will be referred to hereinafter by the cultivar name`Hendryetta`.
Clematis is an important commercial genus with a large number of cultivar hybrids accumulated over a long period. The Inventor feels that modern gardens are unsuited to the vigorous large-flowered hybrids mostly in commerce. In 1990, theInventor commenced a formal breeding program in Boskoop, Holland, whose purpose is to produce free-flowering Clematis plants that are easy to propagate and which are shorter in eventual height and which flower at a shorter height than many cultivars ofClematis in commerce.
In 1992, the Inventor successfully pollinated the female parent plant Clematis hybrid `Purpureostriata` (unpatented) with male parent plant Clematis hybrid `Aljonushka` (unpatented). Clematis `Aljonushka` has been granted an Award of Gardenmerit by The Royal Horticultural Society of England. Very few seeds resulted and one seedling, later named `Hendryetta`, was selected in 1996 as having distinct and desirable characteristics, namely, a tidy and very upright habit, tendency to bearflowers along the stem rather than predominantly at the terminals, and flowers which are a light purple color and which are fragrant.
When compared with the male parent, Clematis `Aljonushka`, whose flowers are of a similar color, `Hendryetta` is approximately one half to two-thirds shorter in overall height.
When compared with the female parent, Clematis `Purpureostriata`, `Hendryetta` exhibits simple or ternate leaves and is more floriferous. The leaves of Clematis `Purpureostriata` are distinctly pinnate.
Apart from the parental cultivars, the closest comparison variety known to the Inventor is Clematis hybrid `Heather Herschell` whose flowers have tepals which are more recurved and twisting, whereas the flowers of `Hendryetta` are symmetrical andbell-shaped, with little or no reflexing. In addition, the stated height of Clematis `Heather Herschell` is in the range 2.0 m to 2.6 m whereas the typical height of `Hendryetta` is 1.0 m to 1.8 m.
The first asexual propagation of `Hendryetta` was accomplished by the inventor in 1996 in a cultivated area of Boskoop, Holland, using softwood cuttings. After conducting successive cycles of asexual reproduction, the Inventor has determinedthat new cultivar `Hendryetta` is stable and reproduces true to type.
An application for a grant of European Community Plant Breeders Rights was filed for `Hendryetta` on Nov. 8, 2002, Application Number 2002/1772. A grant of European Community Plant Breeders Rights was issued on Jun. 7, 2004, Ser. No. 13548.
`Hendryetta` was first exhibited to the public at the Plantarium Exhibition, Boskoop, The Netherlands, on Aug. 20, 2003 at which it was awarded a prize for "Best Novelty". The first orders for purchase of plants of Hendryetta were taken duringthe Plantarium show and the first delivery of a plant of `HENDRYETTA` took place on Sep. 2, 2003.
SUMMARY OF THE INVENTION
The distinguishing characteristics of the new Clematis cultivar `Hendryetta` are as follows. In combination, these traits set `Hendryetta` apart from all other existing varieties of Clematis known to the inventor. Clematis `Hendryetta` exhibitslight purple flowers. 1. Clematis `Hendryetta` is floriferous. 2. Clematis `Hendryetta` is readily propagated using softwood cuttings. 3. Clematis `Hendryetta` exhibits an upright to semi-climbing habit. 4. The flowers of Clematis `Hendryetta`are elegant, symmetrical, bell-shaped. 5. The flowers of Clematis `Hendryetta` are fragrant. 6. Clematis `Hendryetta` exhibits medium to dark-green foliage.
`Hendryetta` has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
BRIEF DESCRIPTION OFTHE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new Clematis variety `Hendryetta` showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differfrom the color values cited in the detailed botanical description, which accurately describes the actual colors of the new variety `Hendryetta`.
The drawing labeled as FIG. 1 illustrates a whole plant which is approximately fifteen months old from a cutting. The cutting was rooted in a frost-protected greenhouse in spring 2003, potted outside in a 1-liter container in summer 2003, cutback to 15 cm above the pot in the fall of 2003, over wintered under frost-protected glass, and allowed to grow and vine and flower outside in the spring and early summer of 2004. The entire growth cycle took place at the Inventor's nursery in Boskoop,The Netherlands.
The drawing labeled as FIG. 2 presents a close up view of the flowers and illustrates the two-tone coloration of the upper surface of the tepals and the red-purple coloration of the peduncles.
Both drawings were made using conventional techniques and although foliage and flower colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the Clematis cultivar named `Hendryetta`.
Data was collected in Boskoop, Holland from a 15 months old plant which had been grown as follows: A cutting of `Hendryetta` was rooted in a frost-protected greenhouse in spring 2003, potted outside in a 1-liter container in summer 2003, cut backto 15 cm above the pot in the fall of 2003, over wintered under frost-protected glass, and allowed to grow and vine and flower outside in the spring and early summer of 2004. The entire growth cycle took place in Boskoop, The Netherlands.
